To all 'LLITLO'H'L it may concern:

I? it known that we, Cnannn'cn J. BROWN and QLAUDE l1, llnown, citizens oi the United citates, and residents oi Chicago, county oi? Cool; and State oi Illinois, have invented new and useful Improvements in Machines for Forming Paper Receptacles, oi which the following is a specification, the principle ol the invention being heroin explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

@ur intention relates to machines for forming paper receptacles and particularly to machines adapted to glue, string and form or fold up into proper shape prepared blanks intended for oyster pails, ice cream buckets, etc More particularly our said improved machine relates to automatic mechanism of this character which shall be economically built and assembled in the first instance, which is designed to i uiuition .vithout easily being injured or getting out of adjustment, which shall be thorough in its og'ieration, and which shall have-a capacity for a very large productiol'l in any given time. A The annexed drawings and the following description set forth in detaii certain means embodying our invention, the disclosed I1l8LL1lb';llJIlQ(61, constituting but one o t various mechanical forms in which the principles oi the invention may be app lied.

In said annexed drawin s:

Figure 1 represents a ijront elevation of our improved machine, completed pail havinc; just been ejected from the bottom thereof and another blank being shown in dotted lines approximately mid'tvay the top and bottom of the machine, Figure 2 represents an elevation of the left side of the machine; Figure represents a vertical section taken through the center of the machine and loot:- ing toward the right side thereoi; l igurc l isa plan view, taken in the plane indi ted bv the line lV ll Figure l, of a part oi? the top of the machine, illustrating the pulling from a magazine by suction of a blank about to be started through the machine certain feeding rolls plainly shown, said view being upon a scale approximately three times as large as that used in the preceding .iigures; if gure 5 represents a transverse section of fragmentary part of the machine Specification. of Letters Patent.

and taken in the plane indicated by the line V-V, Figure 4; Figure 6 represents, upon the same scale as that used in Figure 4, a vertical longitudinal section of upper parts oi the machine, said View looking toward the right oi" the machine and being taken in a plane somewhat beyond the center line certa n disappearing fingers and the cam operating them, hereinafter fully described, being omitted so that certain shear cams can be clearly shown; Figures 7 and 8 represent, upon said enlarged scale, fragmentary vertical sections of said disappearing fingers and the cam for actuating them and of said shears and their actuating cams, the parts shown in Figure 8 being similar to certain parts shown in Figure 6 but in the relative positions Where the shears have just been closed and have cut the tape, hereinafter more fully described, the planes in which said figures are taken being indicated by the lines VlL-Vll and VIIIVIII, respectively, Figure Figure 9 is a front elevation of the upper part of the machine, upon said enlarged scale, showing, however, only the lower part of the structures shown in Figure 6; Figure 10 represents, upon said enlarged scale, a plan section taken from the two planes designated by the lines X X, Figure 6, of a threading device, hereinafter more hilly-described, this View showing the position just after certain grippers have tal-:on hold of the tape, the View also showing the cams and connected parts for operating the shears and disappearing fingers; Figure ll represents a siniiiarview of the threading device when the grippers are pulling the tape bacl: around certain stop pins hereinafter more fully described; Figures 12,13, is and if) show how the gripper jaws are opened to grasp the tape and how they move back without opening, l igure 12 being a plan riew as the vertical part ol the is trilrinp gainst a latch hereinafter more y described, ligure l3 showing the jaw partly opeiied by the'latch, said jaw remaining open until the front of the gripper passes by the plane ofthe tape and both above and below the latter, Figure is showing the relative positions when the vertical part of the jaw has just slipped off the latch and the spring has closed the g ippers on the tape,

and Figure showing the relative positions Cir when the grippers are moving back with the tape, the pivoted latch having swung back and allowed the grippers to pass without being opened; Figure 16 represents a view of the threading device similar to Figures and 11, this view showing the position just after the vertical part of the gripper jaw has been pushed back by certain releasing fingers and the tape has been released; Figure 17 represents an elevation of the gripper jaw, taken from the plane indicated by the line XVII-XVH, Figure 19, the dotted line position showing how the upper gripper aw is opened by the pivoted latch mentioned in Figures 12 to 15; Figure 18 represents an elevation of the gripper jaw, taken from the plane indicated by the line XVIIL-XVHI, Figure 17 Figure 19 represents a plan view of the gripper jaw and its bracket, said Figures 17, 18 and 19 being upon a scale twice the size of that used in Figure 16; Figures 20, 21, 22 and 23 represent motion studies of a tape measuring device, showing four different positions of a pulling device, the details of which will be hereinafter more fully given, Figure 20 representing the pulling device at its extreme right position, after it has taken hold of the tape and is just starting to pull the same across the front of the machine, Figure 21 showing the pulling device crossing the front of the machine with the tape, moving toward the left, Figure 22 showing the pulling device at its extreme left position with the tape, and Figure 23 representing the pulling device moving to the right to secure more tape, all of said views being upon the enlarged scale used in Figure 16; Figure 24 represents an elevation of fragmentary portions taken from the plane indicated by the line XXIV-XXIV, Figure 23; Figure 25 represents a plan view of the elements shown in Figure 24; Figure 26 represents a longitudinal section taken in the plane indicated by the line XXVIXXVI, Figure 23; Figure 27 represents certain parts shown in Figure 26, upon an enlarged scale; Figure 28 represents a longitudinal section taken in the plane indicated by the line XXVHI rl -ZVIH, Figure 21; Figure 29 represents a transverse section taken in the plane indicated by the line XXIXXXIX, Figure 21; Figure 30 represents atransverse section taken in the plane indicated by the line XXX-XXX, Figure 21; Figures 31 and 32 represent hori- Zontal sections of the two jaws of a tape guiding device, one of said jaws being pivoted and two different positions thereof being shown; Figure 33 represents, upon a scale one and one-half times the size used in Figure 1, a plan section of the lower part of the machine looking from the rear toward the front, certain projecting mechanism, hereinafter more fully described, for pushing the formed pail out of the machine,
